Sector Overview

WONE in
Professional Services.

Professional services firms are among the fastest-growing acquirers and cross-border expanders in the world. Law firms merging with international counterparts, accounting practices acquiring in new markets, consulting firms establishing overseas offices — all face the same complex professional services needs as their commercial clients, with the added dimension that they need a genuinely independent external adviser.

WONE's professional services sector practice provides genuinely independent external advice to professional services firms — free from the conflicts that arise when a firm's competitors or potential merger partners are also its advisers. WONE partners understand the specific commercial dynamics of professional services firms: partnership structures, goodwill, client portability, and the regulatory requirements that apply specifically to law firms, accountants, and other licensed professionals.

How WONE works Submit a brief

International merger and combination — legal and regulatory complexity

A law firm or accounting practice combining with an overseas counterpart faces regulatory approvals in every jurisdiction involved, partnership law issues across multiple legal systems, and client notification requirements under professional conduct rules that vary between jurisdictions.

Partner admission, retirement, and lateral movement across borders

International professional services firms managing partners across multiple jurisdictions face complex issues around partner equity, restrictive covenants enforceable in different legal systems, retirement provisions that vary between jurisdictions, and the tax consequences of partner mobility.

Regulatory compliance for licensed professionals across jurisdictions

Law firms, accountants, and other licensed professionals operating across borders must maintain professional regulatory compliance in every jurisdiction where they practise — AML, data protection, anti-bribery, and sector-specific professional conduct rules that differ between regulators.

Tax structuring for international professional services partnerships

Partnership structures operating across borders create complex personal and corporate tax obligations — allocation of profits between jurisdictions, partner mobility tax, VAT on cross-border professional services, and transfer pricing on inter-office transactions.
